You should consider <string> instead, as you can do this:
string x = "hello";
string y = "world";
if(x!=y) //this is much, much easier to use and read than strcmp.
cout<< x<<" " << y << endl;
c-strings are good to know so you can read old code and use them when necessary, but usually string is cleaner. strstr's bool result is occasionally better than string's find. Most everything else is equal or favors string.
